Syntax highlighting themes

Description

This object can be used to set or get themes in knitr for syntax
highlighting.

Usage

knit_theme

Format

An object of class list of length 2.

Details

We can use knit_theme$set(theme) to set the theme, and
knit_theme$get(theme) to get a theme. The theme is a character
string for both methods (either the name of the theme, or the path to the CSS
file of a theme), and for the set() method, it can also be a list
returned by the get() method. See examples below.

Note

The syntax highlighting here only applies to ‘.Rnw’ (LaTeX) and
‘.Rhtml’ (HTML) documents, and it does not work for other types of
documents, such as ‘.Rmd’ (R Markdown, which has its own syntax
highlighting themes; see http://rmarkdown.rstudio.com).
